How many genes make up the human genome?

The human genome has 23 chromosome pairs with a total of about 3 billion DNA base pairs. There are 22 autosomal chromosomes plus the sex determining X and Y chromosomes, to make 23 pairs. There are 22 autosomal chromosomes plus the sex determining X and Y chromosomes, to make 23 pairs. read more

The human genome has many different regulatory sequences which are crucial to controlling gene expression. Conservative estimates indicate that these sequences make up 8% of the genome, however extrapolations from the ENCODE project give that 20-40% of the genome is gene regulatory sequence. read more

The human genome has been estimated to have 20,000 - 25,000 human protein - coding genes. Before it was thought that the number of genes in the human genome was about 100,000, but with better and more advanced gene finding technology, this number has been revised down to the current estimate, and could continue to drop further. read more

The human genome of Homo sapiens is stored on 23 chromosome pairs. 22 of these are autosomal chromosome pairs, while the remaining pair is sex-determining. The haploid human genome occupies a total of just over 3 billion DNA base pairs that means 6 billion base pairs per diploid cell. read more
